Abraham, Anju. “Understanding Vaccines.” PublicHealth. Accessed 14 Mar. 2017.
In this source titled Understanding Vaccines that has a total of 5 subheadings which are about a
vaccine timeline, how they work, what goes into one, CDC recommended vaccines, and myths
debunked. The vaccine timeline starts us off at “Prior to the 15th Century” and then moves us
through century by century, concluding with a future of vaccines. The next subtitle, How Vaccines
Work, talks about how the vaccines train the immune system to recognize and combat
pathogens, and also how they protect an entire population once enough people are immunized.
This section talks about the different kinds of vaccines, as well as different ways to administer
them. The next section titled What Goes Into A Vaccine? looks at the ingredients of vaccines,
which include adjuvants, antibiotics, preservatives, stabilizers, antigens, and lists 6 common
ingredients with a description of their purpose and safety. The CDC-Recommended Vaccinations
section lists the vaccines that are required to enroll in public schools and college, and explains
what each is for and a description of what it is protecting you from. The last section, Vaccine
Myths Debunked, lists 8 common myths and explains why each is false. Some of the myths included
are “Vaccines contain unsafe toxins,” “Vaccines aren’t worth the risk
In comparison with Thimerosal in Vaccines, both confirm that thimerosal has been used as a preservative
in vaccines since the 1930’s, and how it has been removed or reduced from all vaccines
except for the influenza vaccine, and even that has the option to come without the preservative.
They both answer the question of why preservatives are needed in vaccines, and that is to prevent
growth of dangerous bacteria or fungus that would cause contamination. This source offers me
something that the other source did not, a timeline of vaccines in general, the large scale effect of
vaccines, which ones are recommended by the CDC as well as why they are, and it also answers
the common myths that people may believe. Overall, this source is reliable and objective, and the
goal of the source is to educate the reader about the history of vaccines as well as how it works.
This source will fit into the narration section of my research, as it has extensive information on
the history of vaccines, explains how they work, what goes into creating a vaccine and why, vaccines
CDC recommends everyone gets, as well as common vaccine myths. It changed the way I
think about my topic by having a timeline of vaccine progression through the centuries, and also
other common vaccine ingredients that may be a reason for some parents to fear vaccinations.
